With the continuous maturation of the HarmonyOS ecosystem, Huawei's HUAWEI HiCar in-car connectivity solution has ushered in a milestone update—the V6.0.0 certification system has officially launched.
On March 31,2026, Huawei officially released the implementation rules for the new acceptance criteria V6.0.0 and the acceptance application materials. This is not just a simple version iteration, but a comprehensive upgrade covering testing standards, processes, documentation, and core experiences, which will bring automakers, hardware partners, and end-users a more seamless, intelligent, and smooth new in-car connectivity experience.
1、Comprehensive upgrade of certification benchmarks: optimized for the latest HarmonyOS to deliver flagship-level performance
HiCar V6.0.0 first raises the hardware and software compatibility threshold, ensuring consistent user experience from the source.
l Test phone upgrade: It is mandatory to use Huawei's latest Mate/P series commercial flagship device from the current or previous year to ensure peak performance on mainstream high-end devices.
l System version update: The testing benchmark has been upgraded from HarmonyOS 4.x+5.x to HarmonyOS 4.x+6.x. Products must demonstrate forward-looking compatibility to keep pace with HarmonyOS iteration cycles and ensure long-term stable usability.
2、Clear process and timeline: parallel transition, full switchover by July 1
To avoid affecting the progress of automotive projects, Huawei has set a smooth transition window with clearly defined time nodes:
1. Parallel transition period (March 31,2026 – June 30,2026):
During this period, V5.0.0 and V6.0.0 standards will be implemented concurrently. For existing collaborative projects or equivalent projects, graphic equivalence acceptance based on V5.0.0 standards is permitted.
2. Full transition period (starting from July 1, 2026):
Switch to V6.0.0 test cases. If the project cannot complete certification testing by July 1, switch to the new standard test cases promptly to avoid project delays.
Important note: Projects with statuses such as "Vehicle model approval not passed" or "Cooperation access granted" must follow this timeline for standard switching.
1、Certification package update: Four core documents newly released
With the upgrade of standards, the application material package has been comprehensively renewed. The old version of the V5.0.0 series documentation will gradually be phased out. Starting from March 31,2026, all acceptance applications must be based on the new template version V6.0.0:
1. HUAWEI HiCar Vehicle Access Acceptance Test Report (Institutional Edition) -Product Name-V6.0.0
2. HUAWEI HiCar Vehicle Access Acceptance Self-Test Report_V6.0.0
3. HUAWEI HiCar Ecosystem Product Certification Type Application Form V6.0.0
4. HUAWEI HiCar Hardware and Software Resource Constraints Table_V6.0.0
Among these documents, the 'Software and Hardware Resource Constraints Table' serves as a critical self-check file prior to certification. Version V6.0.0 imposes more detailed requirements for this document. Partners are advised to thoroughly verify it before submitting applications to ensure hardware resources comply with V6.0.0 constraints.
2、Core Changes in Test Cases: Focus on "3D Vehicle Control" and "Full-Scenario Interconnection"
V6.0.0 not only supplements existing standards but also expands the experiential dimensions. The new test cases incorporate evaluations of multiple critical scenarios to enhance deep integration between smartphones and vehicles. Key newly added use cases include:
1. 3D Vehicle Control: A standout feature of V6.0.0. The testing will evaluate the fluidity, response speed, and rendering quality of 3D visualized vehicle control, ensuring precise and visually stunning control of physical vehicles within the digital environment.
2. File transfer: Enhance data exchange capabilities between smartphones and in-vehicle systems, while evaluating transmission stability and efficiency for large files and multi-format data.
3. Mobile Desktop and UI: Conducted specialized testing for seamless mobile desktop navigation to ensure the screen mirroring interface's UI compatibility and interaction logic meet HarmonyOS native experience standards.
4. Audio and Screen Mirroring: Enhance audio transmission fidelity and low latency performance, while testing the stability and image quality of screen mirroring functionality.
5. Wireless connectivity: Focus on optimizing connection stability, interference resistance, and fast reconnection performance.
3、Select Zhongle Certification: Embrace Change, Win Together for a New HarmonyOS Experience
